Place the sliced butter into a 9 X 9-inch baking pan.
Put the pan in the oven and turn it on to 450 degrees F. Be sure to check the butter as it melts to prevent it from browning. Remove pan from oven after butter has melted.
In a large bowl, mix together the Bisquick, Greek yogurt, and 7-Up with a wooden spoon until well combined.
Using a small amount of flour for your hands, divide the dough into 9 equal amounts and place into the baking dish. The dough will expand as it bakes, so don't fret if all spaces in the pan are not completely filled in.
Bake for 12- 15 minutes, or until top is lightly golden.
Remember to be checking that butter melting in the dish so that it doesn't brown. Browned butter is good, but not for this recipe - we want it yellow. If it's browned before the dough is added, there's a likely chance the butter will burn and good biscuits with burnt butter will not be well received at dinner. Trust me.
